【问题描述】：

我对 AS3 还很陌生。无论如何，我尝试在单击时删除动态创建的子影片剪辑。当一个污垢块被点击时，它是“世界”的一个子动画片段，我想将其移除。

我尝试了各种使用 removeChild 删除它的方法。我还尝试在创建影片剪辑的 for 循环内部/外部移动函数。

var blockCount:Number = 0;
var blockArray:Array = [];

var world:MovieClip = new World();
world.x = 50;
world.y = 50;
world.name = "world";
addChild(world);

for(var i:Number=1;i<=100;i++)
    blockCount++;
    var tempGrassBlock:MovieClip = new GrassBlock();
    tempGrassBlock.x = i*16;
    tempGrassBlock.y = 256;
    tempGrassBlock.name = "b"+blockCount;
    world.addChild(tempGrassBlock);

    tempGrassBlock.addEventListener(MouseEvent.CLICK, removeBlock);
    function removeBlock(event:Event)
        world.removeChild(getChildByName(event.target.name));
    

感谢您的帮助。

【参考方案1】：

试试这个

function removeBlock(event:Event)
    world.removeChild(event.currentTarget as DisplayObject);

【参考方案2】：

任何函数定义都不应该在 for 中。我在你的代码中改变了它，并在下面重写了一点：

var blockCount:Number = 0;
var blockArray:Array = [];

var world:MovieClip = new World();
world.x = 50;
world.y = 50;
world.name = "world";
addChild(world);

for(var i:Number=1;i<=100;i++)
    blockCount++;
    var tempGrassBlock:MovieClip = new GrassBlock();
    tempGrassBlock.x = i*16;
    tempGrassBlock.y = 256;
    tempGrassBlock.name = "b"+blockCount;
    world.addChild(tempGrassBlock);

    tempGrassBlock.addEventListener(MouseEvent.CLICK, removeBlock);



function removeBlock(event:MouseEvent)
    trace("Is click really working? This target name is " + event.currentTarget.name);
    world.removeChild(event.currentTarget));
